At Achema 2018, LEWA will be presenting the new model in triplex design with three different pump heads. A more in-depth experience will be made possible by an augmented reality animation that gives the viewer a glance into the inside of the pump.
"The gap between our LDG and LDH Ecoflow process pump drive units is relatively large. When customers came to us looking for a pump just slightly more powerful than the LDG, we had no choice but to offer them the much more powerful—and much more expensive—LDH," explains Thomas Bökenbrink, Lead Product Manager Pumps at LEWA Leonberg. As a result sales and product management initiated the development of a new performance rating that was meant to function as an intermediate unit; the LDZ at 15 kW. The Research and Development Department called upon internal divisions such as assembly and the service and purchasing departments to make the product market-ready in the shortest amount of time possible. Various worm shaft bearing concepts were analyzed regarding service life, heat development, price, manufacturing and assembly.
The cast parts, which are subject to a complex manufacturing process, were designed with process reliability in mind. "During development, we were able to gain advantages in the design. The components have been designed in a way that is geared toward the manufacturing processes and optimized using state-of-the-art technology," Bökenbrink explains. "In the future, we want to gradually start using this optimized production process for additional drive unit models."
One pump - countless applications
"The new size allows us to be more flexible and meet different requirements," Bökenbrink adds. "This way, the customer receives the usual product quality adapted optimally to his needs." The pump is available as a single or multiplex drive unit and can be combined with other types from the Ecoflow portfolio.
With a hydraulic output of 15 kW and a flow rate of up to 18 m3/h, the new process pump can handle many applications in areas that include the chemical and the petrochemical industry as well as refineries. These industries work with corresponding media and high-pressure processes and require the machines to run reliably and precisely 24/7 all year long. In addition to process industries, the LDZ is used in the oil and gas sectors, such as for a variety of condensates or injection packages for chemicals. There are no system requirements for using the pumps in this way.
Exhibit with augmented reality function
Like most other models from the Ecoflow modules, the LDZ can be customized to individual applications. This customization means that wetted materials and process valves can be adapted specifically to the pumped fluid as needed. Furthermore, implementing a heating or cooling jacket or a remote head solution is possible at extreme temperatures. A total of five different pump head types are available. The pump can also be adapted to the food and pharmaceutical industries. Customized constructions are also available for special requests that are not yet available in the product range.
At this year's Achema trade show, LEWA will present the new model size; a multiplex pump equipped with three different pump heads. "The LDZ3 exhibit illustrates the versatile application options of our series: The remote pump head is suited for high temperatures in refineries. On the other hand, the M800, our high-pressure pump head (up to 1,000 bar) is being used to handle enormous pressures, such as those in reactor pumps. The model is completed by the M900, our pump head for a wide variety range and high flow rates," explains the product manager. The M900 design on display is the hygienic version for the food and pharmaceutical industry. In order to get a better understanding of the pump, LEWA is making an augmented reality app available on a tablet. It shows the inside of the exhibit in 3D and uses animation to simulate the functionality of the pump and various operating conditions. This way, those interested can get an insight of the functionality.
